PURPOSE:To eliminate the troubles such as damage of fiber caused by moisture condensation, and to prevent the degradation of staple diagram, by substituting the air contained in the bundle of continuous filaments with dried gas, and passing the bundle through a low-temperature atmosphere. CONSTITUTION:A cooling tank A for cooling the tow 1 is placed at the inlet-side of the stretch-breaking machine 4, and the air-substitution tank B is placed at the inlet-side of the cooling tank A. The substitution tank is filled with dried air having a dew point of <=-5 deg.C, and the air contained in the tow is substituted with the dried air during the passage of the tow 1 in the substitution tank B. The condensation of moisture during the passage of the tow through the low- temperature atmosphere of <=-5 deg.C in the cooling tank, can be minimized by this process.
